electric interurban was running from Newark to Granville. The line wasn't opened to Zanesville until 1903 due to difficulties cutting a pathway through the gorge. An interurban tunnel high and long was blasted through solid rock to complete the job. The interurban ran on the opposite side of the Licking River from the B&O Railroad. The interurban was short-lived due to the rising popularity of the automobile. The last Ohio Electric Interurban car ran through the gorge on February 15, 1929. Dillon Dam (1961) Construction of Dillon Dam began in June 1946, but work was halted due to lack of funds, and then a shortage of materials due to the outbreak of the Korean War. Construction on the dam resumed in 1958 and it was completed in June 1961. The dam protects the Muskingum Valley, including the cities of Zanesville, McConnelsville, and Marietta. Unfortunately, the reservoir formed by the dam completely submerged Claylick and required that most of the town of Toboso be torn down. Opposition to the project was fierce for that reason, but the benefits of the dam served a wide constituency and construction was not prevented.
